A new fast algebraic estimation scheme in time domain is proposed for amplitude, frequency and phase parameters in electric power system signals with multiple frequency harmonics. Time domain integral operators are properly used in the synthesis of the proposed parametric estimation approach. In this fashion, time derivatives of signals and initial conditions of the system are unnecessary. Analytical and numerical results confirm the effectiveness of the proposed algebraic approach for fast and simultaneous estimation of amplitude, frequency and phase parameters of harmonics, inter-harmonics and sub-harmonics on electric power system signals.
